Abstract

This research study focuses on production of bio-oil through slow pyrolysis of rice husk (RH) by varying heating rates while maintaining other reaction parameters: Feedstock size, reaction temperature and nitrogen flow rate (carrier gas). The optimum reaction condition for the slow pyrolysis of husk (RH) giving the maximum liquid yield is found to be slow pyrolysis at heating rate of 20 °C/min, feedstock size of 0.25-0.50 mm, reaction temperature of 500 °C and nitrogen flow rate of 100 ml/min. Highest average liquid yield of bio-oil obtained is 35.38 wt%. The bio-oil produced at the optimum condition is also characterized and found that it basically has higher pH, viscosity, density value, elemental compositions and higher estimated HHV compared to bio-oil produced at other heating rates. GC-MS analysis proved that bio-oil produced at heating rate of 20 °C/min has more aldehydes, acids, ketones and phenol compounds.
